This is the sketch of one of my unnecessary inventions. I divided my sketch into 5 different parts. The first part of the sketch contains the most basic and intuitive information of the product, which has the extra space beneath the hole in a plate. The extra space of the hole is controlled by an adjustable holder, which is colored in black. The next 4 steps explain how my invention is utilized.
Step 1
The extra space of the plate is closed and locked by the holder, in order to enable users to exercise with the weights.
Step 2
The extra space is opened by removing the holder to the right.
Step 3
The holder is locked and fixed in the right side of the extra space so that the plate doesn’t move around along the barbell while removing.
Step 4
The final step is to lift up the plate and remove it without any friction from the ground.
Now, users can easily remove the plate despite the barbell staying on the ground.
